I am considering whether or not to use a HTPC in my home theater. One big issue is aspect ratio control. Is there any way of using a HTPC to take an anamorphic image from a DVD and stretch it to its proper 1.85 or 2.35 aspect ratio such that the full panel resolution of a 4:3 projector is utilized (i.e., can it perform the function of a panamorph or ISCO lens)? Can a HTPC be used to expand letterboxed movies to fill a wide aspect ratio screen? In other words, if I were to use a 4:3 projector with a 2.35 screen can I set up the projector so that it maintains constant height while switching between different aspect ratios?
